CO2 welding wire ER70S-6

welding wire
1.have excellent mechanical performance
2.such as ships,vehicles,bridges,boils and buildings etc
General Description: the welding wires has the characteristics of excellent technical performance,fast melting speed, high efficient fusion, stable electric arc, less welding splash,favorable wetness performance,average & beautiful welding seam,good anti-oxygenic & anti-corrasive property, less sensitive to the atmosphere holes. It can be shielded by means of DC(±), CO2 or the combination of Ar+CO2 5-10%. Easy to operate and is suitable for the automatic and semi-automatic omnibearing welding. Applications: Mainly used in welding of carban steel, low alloy steel & 500MPa grade low alloy high intensity steel,Widely used in vehicle, building, bridge, shipbuilding & pressure vessel industry,it can also be used in the high speed welding of thin steel plate and pipeline.

CO2 Gas-sheilded welding wires have excellent mechanical performance such as fast depositing speed,high depositing effciency,stable arc,little splash,good welding seam.
suitale for all-position welding work.
widely used to welding low carbon steel and low alloy steel structure,such as ships,vehicles,bridges,boils and buildings etc
